WhatsApp recently introduced a 'Delete for Everyone' option which allows users to delete delivered message on the receiver's smartphone. However, users can simply access the deleted messages, even if the message has not been opened, thanks to a few apps.

One such as is called ‘Notification History’. The app, which is available on the Google Play Store, will create a shortcut on your home screen. You can tap the icon to open the notification registry of the Android system. You will have to search for the notification which says WhatsApp. The blog points out, “the message will be in the line that says "android.text", as you can see in the illustrative images at the beginning.”

Another app, called Nova Launcher will also do the trick. All you will have to do is long press on an empty area on the home screen. Tap on ‘Widgets’. Later, long press on ‘Activities’ and drop when you jump to the home screen. A list will appear – click ‘Settings’. Lastly, in the sub-list, tap the ‘Notification Log’ to create the shortcut on the home screen. You can then enter the Android notification history and search for the WhatsApp deleted messages respectively.
